No really, how many defensive bigs have impacted a championship series more than their teammate, which would be an explosive guard?

I will wait for the answer.

Did you intend on the answer pun? If so, that's pretty good. Quite a few. Typically, the closer one gets to the basket the more likely he is to score. Therefore a dominant center, who can guard the rim, forces teams to take more outside shots, which are less likely to go in. It's basketball 101.
